First of all, I am no color expert, at all. Anyway, I always assumed Tungsten is bay because he has black points. However, he does not have black points on his ears at all. His coat is pretty bleached right not because he is out 8 hours a day, weather permitting.
I have only have him for 4 months. His winter coat was so dark it looked black. When he shed, but before the weather permitted good turnout, he stayed pretty dark, but now he is really bleached and I have no idea. His face does not bleach and he does not have dark points on his ears.
